| Title | North Carolina Agreement State Report - Leaking Sealed Source |
| Event Description | The following information was obtained from the State of North Carolina via email:
On November 18, 2011, the RSO of Research Triangle Institute (RTI), License Number 032-0131-1, performed a leak test on a sealed source. The results of the leak test revealed greater than 0.005 microcuries of removable contamination. The leak test showed 0.00517 microcuries of removable contamination. Subsequent surveys continued to show elevated results. The survey was performed with a Packard 1900 TR liquid scintillation counter, S/N 103761, calibrated Aug. 24, 2011. The source was a Ni-63 Electron Capture source. It had been removed from service and placed in storage in 2008. The source was being leak tested to prepare for disposal. Upon determination that the source was leaking, the RSO double-bagged the source, removed it from storage and segregated it, and contacted the waste broker for instructions on source disposal. The RSO performed contamination surveys of the storage area and the area is clean. Source information: Isotope: Ni-63, Quantity: 11.3 mCi, Mfg: Franklin GNO Corporation, Drawing No: 801-023, Serial Number: 37, Source date: October 20, 1975 The licensee met all reporting requirements for the 5-day notification of a leaking source and is preparing a report with additional information. |
